Diagnosis

Males of C. huila sp. nov. resemble those of C. paramo by a large cymbium that is more than twice as long as the tibia length, and by a similar poorly pronounced dorsal tubercle on the palpal femur ( Fig. 3H–J ), but can be distinguished by having a anteriorly directed embolar base ( Fig. 4D–F ), instead posteriorly directed as in C. paramo (see Platnick 1994a: figs 39–41). Additionally, the embolus tip is larger than that of C. paramo , presenting a median expansion, widening tip and enlarged opening ( Figs 3H–J , 4D–F ).

Etymology

The specific epithet is a toponymic, referring to the type locality.
